You are watching: As the temperature of a substance increases
TL;DR (Too Long; Didn"t Read)
Temperature has actually a straight effect on whether a problem exists together a solid, liquid or gas. Generally, raising the temperature transforms solids into liquids and also liquids into gases; reduce it transforms gases into liquids and also liquids right into solids.
At short temperatures, molecular activity decreases and substances have less interior energy. Atoms will settle right into low power states relative to one another and also move an extremely little, i m sorry is properties of hard matter. As temperatures increase, extr heat energy is applied to the constituent parts of a solid, which causes added molecular motion. Molecules begin to push versus one another and the in its entirety volume that a problem increases. In ~ this point, the issue has gone into the liquid state. A gaseous state exists once molecules have soaked up so much heat energy because of increased temperatures that they are cost-free to move around one another at high speeds.
The allude at which issue subjected come a certain temperature under conditions of constant pressure starts to adjust its step is referred to as the phase change threshold. At this temperature, every bit of the substance exposed come the heat will readjust its state. A change from to a solid to a fluid occurs in ~ the melting point, and the shift from a liquid to a gas takes place at the boiling point. Vice versa, the minute of readjust from a gas to a liquid is the condensation suggest and the shift from a fluid to a heavy takes ar at the freezing point.
A substance might undergo phase change from a solid come a gas or native a gas to a heavy if the temperature it is exposed come is changed really quickly. If the temperature approximately a heavy is raised very quickly, it have the right to sublimate, or phase adjust from a solid to a gas without existing together a liquid. In the opposite direction, a gas the is all of sudden supercooled can undergo complete deposition.
If push is constant, the state the a substance will depend entirely on the temperature the is exposed to. Because that this reason, ice cream melts if taken the end of a freezer and also water boils the end of a pot if left at too high a temperature for also long. Temperature is just a measure up of the amount of warm energy current in the surroundings. As soon as a problem is inserted in next site of a different temperature, warm is exchanged between the substance and also the surroundings, causing both to attain an equilibrium temperature. So once an ice cube is exposed come heat, that is water molecule absorb heat energy from the surrounding atmosphere and also begin come move an ext energetically, bring about the water ice to melt right into liquid water.
